I have A Norlin Era Epi Acoustic...........its very nice
I don't know if the above pic is intended to depict a "The SG", but I'm not sure it is.
A "The SG" had an overlay the same color as the guitar body (walnut color) and the truss rod cover was engraved with "The SG".
The pickup selector is in the same position normally found in the "The SG" guitars. But, the headstock overlay is different.
